Pipe  Fit    -­‐    Split  Repair  Sleeve

       Split  sleeves  are  widely  used  for  making  repairs  to  a  variety  of  high  or  low  pressure  and  high  or  low  temperature  pipelines,  containing  oil,  water,  gas,  steam  and  chemical  fluids.  

The  clamp  halves  are  joined  by  bolts  to  form  a  high  integrity  pressure  vessel  around  the  damaged  or  leaking  pipe.

Sealing  is  provided  by  elastomer  seals  of  the  highest  quality  selected  for  compa?bility  with  the  pipeline  fluid  and  opera?ng  temperature.  

The  Split  sleeves  may  also  be  welded  a@er  installa?on  to  provide  a  permanent  repair.  It  may  be  completely  seal-­‐welded  with  the  pipe  line  in  opera?on.

SafetyThe clamps are fully compensatory pressure vessels, hydrostatically tested to 1.3 times the rated working pressure (as per ASME Sect ion VI I I D iv .1 clause UG-99)

All Clamps are equipped with a 1” NPT vent port.

Design Criteria and Industry StandardsAll split sleeves are tested in accordance with the API Specification 6H, “Specification for End Closures, Connectors, and Swivels”, ASME BOILER AND PRESSURE VESSEL CODE, Section VIII; and with ANSI standards B-31.3, B31.4, & B31.8, where applicable.Certification: EN 10204 3.1

Ease of Installation and MaintenanceAll split sleeves are designed to be installed with the most common tools available and are readily field repairable, including full seal replacement.

EconomySplit Sleeve Repair Clamps are designed utilizing the latest technology, allowing optimization of design techniques and materials, resulting in lower weight, reduced bending tendencies, and a more economical product.

ANSI pressure classes 300, 400, 600, 900 and 1500

Design based on: ASME Sec. VIII, API 6H , ANSI B31.4, B31.8 and Split Sleeve Software 3S)

Design control and stress analysis with Finite Element Package

Body materials: A216 WCB, A216 WCC, A352 LCC, A516 Gr.70 (Suitable for normally corrosive services)

Stud material: A193 Gr. B7Nut material: A 194 Gr. 2H

Coating: Yellow Epoxy Polyamide, standard or Marine epoxy

The highest quality NBR or VITON elastomer seal precisely compatible with the line fluid and ambient temperature will be installed into the split sleeves.

NBR temperature range is from - 20 ̊C to + 80 ̊CHNBR temperature range is from - 20 ̊C to + 150 ̊CVITON temperature range is from - 20 ̊C to + 200 ̊C

Gaskets are replaceable without any special tools.

Girder rings can be installed upon cleints request.

Double Row Sealing (DRS) design is also available. This special design is more suitable for where probableleakage is much costly or dangerous; such as gaseous services & offshore applications.

Weldable split sleevesAll clamps can be fully prepared for welding after installation (welding procedure is available on request).

Heat insulators (parallel to the seals) protect the seals from heat during the welding of the sleeves to the pipe .

Clamps with longer lengths available on request.

This type of split sleeve is designed to be used in hydrogen sulfide (H2S) bearing hydrocarbon service.

For sour services, the body material will meet NACE MR0175
